Den foreliggende opfindelse angår et anlæg af den i indledningen til krav 1 angivne art og en fremgangsmåde af den i indledningen til krav 9 angivne art til opvarmning, emballering og sterilisation af pumpelige, partikelformige 5 fødevareprodukter.The present invention relates to a plant of the kind set forth in the preamble of claim 1 and to a method of the kind set forth in the preamble of claim 9 for heating, packaging and sterilizing pumpable particulate food products.
Dåsekonservering af fødevareprodukter såsom supper, gryderetter, chilier og andre emner er sædvanlige og veletablerede processer. En almindelig klage over sådanne dåsefødevarer angår imidlertid den unaturlige smag, der må tilskri-10 ves dåsekonserveringsprocesserne. Det vil sige, at det er absolut væsentligt, at disse produkter steriliseres tilstrækkeligt for at undgå ødelæggelse, og som en følge heraf har man ved behandlingen været tilbøjelig til at overkoge produkterne for at sikre korrekt sterilisation. Dette skaber igen 15 den overkogte, unaturlige smag, der er karakteristisk for så mange konserves.Cans canning food products such as soups, casseroles, chilies and other items are common and well-established processes. However, a common complaint about such canned foods concerns the unnatural taste that must be attributed to the canning processes. That is, it is essential that these products are sufficiently sterilized to avoid destruction, and as a result, the treatment has tended to overcook the products to ensure proper sterilization. This in turn creates the overcooked, unnatural taste characteristic of so many preserves.
US patentskrift nr. 3.241.475 omhandler en dåsekonserveringsprocedure, der er noget forskellig fra den konventionelle metode. Fremgangsmåden og apparatet, der er be-20 skrevet i dette patentskrift, er blevet udnyttet kommercielt i et antal år som den såkaldte "Flash 18" proces. Ved denne metode pumpes en fødevare, som skal behandles, først gennem et par serieforbundne, ovenstrøms tilførselspumper af vin-getypen, hvorpå produktet enten passerer gennem en indirekte 25 varmevekslerkogeenhed eller gennem en zone med dampinjektion.U.S. Patent No. 3,241,475 discloses a can preservation procedure somewhat different from the conventional method. The method and apparatus described in this patent have been used commercially for a number of years as the so-called "Flash 18" process. In this method, a food to be processed is first pumped through a pair of series-connected, upstream wine-type feed pumps, on which the product either passes through an indirect heat exchanger unit or through a vapor injection zone.
Derpå kan der tilsættes yderligere fugtighed til produktet, og det føres gennem endnu en modtrykspumpe af vingetypen.Then additional moisture can be added to the product and passed through yet another wing-type pump.
På dette tidspunkt kan produktet passere gennem en lynafluf-ter med henblik på at sænke produkttrykket og -temperaturen, 30 hvorpå produktet passerer gennem en fjerde pumpe af vingetypen og ledes til et emballeringskammer. Selve emballeringskammeret har form som en forholdsvis stor, undertryk stående bygning, der rummer dåsekonserveringsudstyr og anlægspersonel. I kammeret fyldes produktet fra aflufteren 35 på dåser på den sædvanlige måde og sendes så til en steriliserings- og afkølingsstation udvendigt for kammeret.At this point, the product may pass through a lightning aerator to lower the product pressure and temperature, whereupon the product passes through a fourth wing-type pump and is directed to a packaging chamber. The packaging chamber itself takes the form of a relatively large, suppressed standing building containing canning equipment and plant personnel. In the chamber, the product from the vent 35 is filled into cans in the usual manner and then sent to a sterilization and cooling station outside the chamber.

Mens den beskrevne "Flash 18" proces har været i brug i et antal år, frembyder den et antal problemer med hensyn til produktsammenhæng, navnlig når det drejer sig om produkter indeholdende store partikler. Specielt skaber 5 brugen af flere pumper af vingetypen til fremdrivning af produktet gennem behandlingsledningen og etablering af modtryk inden i denne uundgåeligt væsentlige trykvariationer og en uensartet trykgradient gennem produktledningen. Som en følge heraf må der med henblik på at undgå førtidig brat-10 kogning (flashing) af produktet være en væsentlig trykforskel mellem damptrykket inden i de indirekte varmevekslerkapper eller som injiceret og produkttrykket. I praksis har denne trykforskel været i området fra 1,0 til 1,4 atm. Ydermere er det, for så vidt som denne høje trykforskel etableres inden 15 i produktledningen, i de fleste tilfælde nødvendigt at lyn-aflufte produktet før det kommer ind i det under tryk stående fyldekammer. En sådan afluftning frembyder naturligvis en anden zone med hurtig trykændring inden i produktledningen ovenstrøms for fyldekammeret og kan i og for sig forringe 20 partikelsammenhængen.While the described "Flash 18" process has been in use for a number of years, it presents a number of problems with regard to product cohesion, especially in the case of products containing large particles. In particular, 5 creates the use of multiple wing-type pumps to propel the product through the treatment line and establish back pressure within this inevitably significant pressure variation and a uniform pressure gradient through the product line. As a result, in order to avoid premature flashing of the product, there must be a significant pressure difference between the vapor pressure within the indirect heat exchanger caps or as injected and the product pressure. In practice, this pressure difference has been in the range of 1.0 to 1.4 atm. Furthermore, insofar as this high pressure difference is established before 15 in the product line, in most cases it is necessary to lightly vent the product before entering the pressurized filling chamber. Such venting, of course, provides another zone of rapid pressure change within the product conduit upstream of the filling chamber and can in itself impair the particle coherence.
Den foreliggende opfindelses formål er at tilvejebringe et anlæg af den i indledningen til krav i angivne art og en fremgangsmåde af den i indledningen til krav 9 angivne art, med hvilke man undgår disse problemer, og med hvilke 25 fødevareproduktet uden brug af indskudte pumper og uden risiko for overkogning og bratkogning med de deraf følgende ulemper såsom sprængning af større partikelformige bestanddele af fødevareproduktet og andre organoleptiske forringelser af dette kan føres fra pumpen gennem produktafgivel-30 sesledningen til dennes åbne afgivelsesende.The object of the present invention is to provide a plant of the kind set forth in the preamble of claims of the kind and a method of the kind set forth in the preamble of claim 9 with which to avoid these problems and with which the food product without the use of inserted pumps and without risk of overcooking and boiling with the resulting disadvantages such as bursting of larger particulate constituents of the food product and other organoleptic degradations thereof can be passed from the pump through the product delivery line to its open release end.
Dette opnås for anlæggets vedkommende ved det i den kendetegnende del af krav l angivne og for fremgangsmådens vedkommende ved det i den kendetegnende del af krav 9 angivne.This is achieved in the case of the plant by the characterizing part of claim 1 and by the method of the characterizing part of claim 9.
35 Herved føres fødevareproduktet gennem produktafgivel sesledningen som en i hovedsagen sammenhængende prop under35 Hereby, the food product is passed through the product delivery line as a substantially continuous plug underneath.

4 lig produktstrøm til pumpen på en portions-kontinuerlig basis.4 equal product flow to the pump on a batch continuous basis.
Den ovenstrøms ende af ledningen 18 er direkte koblet til afgangen fra pumpen 20. Det indledende afsnit af den 5 samlede ledning 18 er igen koblet til tilgangen til en skematisk gengivet varmeveksler 32 med skrabet overflade. Den sidstnævnte varmeveksler er af den art, der markedsføres af Cherry Burrell Company og omfatter udvendige dampkapper til indirekte opvarmning af produkt, som passerer gennem var-10 meveksleren. Selv om det ikke er udtrykkeligt vist på tegningen, vil det forstås, at der kunne være tilvejebragt én eller flere af disse varmevekslerenheder. Når der anvendes flere enheder, vil disse være forbundet i serie.The upstream end of conduit 18 is directly coupled to the outlet of pump 20. The initial portion of the overall conduit 18 is again coupled to the inlet of a schematically rendered scraper surface 32. The latter heat exchanger is of the kind marketed by the Cherry Burrell Company and includes exterior steam hoods for indirect heating of product passing through the heat exchanger. Although not explicitly shown in the drawings, it will be appreciated that one or more of these heat exchanger units may be provided. When multiple devices are used, these will be connected in series.
I alle tilfælde er ledningen 18 koblet til afgangen 15 fra varmeveksleren 32 og strækker sig som vist til den øvre væg af kammeret 14. Et lodret afgivelsesrør 34 er forbundet med den tilgrænsende ende af ledningen 18 med den åbne ende af røret 34 i forbindelse med det indre af kammeret 14 (se fig. 2) . Ydermere er en produktrecirkuleringsledning 36 20 funktionelt koblet til det lodrette rør 34, og der er tilvejebragt en ventil 38 til at lede produktstrømmen enten nedad gennem røret 34 eller gennem recirkulationsledningen.In all cases, the conduit 18 is coupled to the outlet 15 of the heat exchanger 32 and extends as shown to the upper wall of the chamber 14. A vertical discharge tube 34 is connected to the adjacent end of conduit 18 to the open end of the tube 34 in connection with it. interior of chamber 14 (see Fig. 2). In addition, a product recycling line 36 20 is functionally coupled to the vertical tube 34 and a valve 38 is provided to direct the product flow either downwardly through the tube 34 or through the recycling line.
Af fig. 1 vil det ses, at recirkulationsledningen er udformet til at afgive produkt til hver af kedlerne 22 eller 24 efter 25 ønske, og der er tilvejebragt passende ventiler til dette formål.In FIG. 1, it will be seen that the recirculation line is designed to deliver product to each of the boilers 22 or 24 as desired, and appropriate valves are provided for this purpose.
Kammeret 14 foreligger i form af en opretstående, tætnet, hul konstruktion af en størrelse, der kan rumme emballeringsudstyr, der generelt er angivet ved henvisnings-30 betegnelsen 40 (se fig. 2). I den gengivne form er emballeringsudstyret 40 udformet til at forme, fylde og forsegle fleksible emballager dannet af en kontinuerlig bane 42 af en emballeringsfolie af syntetisk harpiks. Sådant forme-, fylde- og forseglingsudstyr er velkendt og er omhandlet i 35 US-patentskrift nr. 2.160.367, hvortil der herom henvises. Desuden er emballeringsudstyret 40, skønt det ikke er udtryk-The chamber 14 is in the form of an upright, sealed, hollow construction of a size capable of accommodating packaging equipment generally indicated by the reference numeral 40 (see Fig. 2). In the rendered form, the packaging equipment 40 is designed to mold, fill and seal flexible packages formed by a continuous web 42 of a synthetic resin packaging film.

Det samlede kammer 14 er yderligere udstyret med 5 kraftdrevne organer såsom en luftkompressor 44 til at etablere overatmosfæriske tryktilstande inden i det indre af kammeret. Størrelsen af dette overatmosfæriske tryk varierer med et produkt, der behandles, men vil typisk ligge fra 0,7 til 3,5 ato. En med en ventil forsynet aflastningsledning 10 46 er ligeledes i forbindelse med det indre af kammeret 14 med henblik på at tillade selektiv trykaflastning af kammeret efter behov.The assembled chamber 14 is further equipped with 5 power-driven means such as an air compressor 44 to establish over-atmospheric pressure states within the interior of the chamber. The magnitude of this over-atmospheric pressure varies with a product being treated, but will typically range from 0.7 to 3.5 ato. A valve relief line 10 46 is also connected to the interior of the chamber 14 to allow selective pressure relief of the chamber as required.
Af fig. 1 vil det ses, at der er tilvejebragt en adgangsdør 48 til kammeret 14 med henblik på at tillade 15 selektiv adgang for vedligeholdelsespersonel til det indre af kammeret. Imidlertid er kammeret ikke udformet for normalt arbejde i og omkring det automatiske emballeringsudstyr 40.In FIG. 1, it will be seen that an access door 48 to the chamber 14 is provided to allow 15 selective access for maintenance personnel to the interior of the chamber. However, the chamber is not designed for normal work in and around the automatic packaging equipment 40.
Til dette formål er et styrepanel 50 beliggende uden for kammeret 14 for at tillade operatørstyring af emballerings-20 apparatet 40 uden indtrængning i kammeret 14.For this purpose, a control panel 50 is located outside the chamber 14 to allow operator control of the packaging apparatus 40 without penetration into the chamber 14.

Der hen-25 vises herom til denne brochure. Kort forklaret er koger/kø-lerindretningen imidlertid udformet til at modtage indiduelle emballager af fødevareprodukter med henblik på at underkaste disse kortvarig højtemperatursterilisation efterfulgt af køling og trykaflastning til omgivelsernes temperatur og 30 tryk. Af fig. 1 og 2 vil det ses, at et kontinuerligt transportbånd 52 tjener til funktionelt at forbinde det indre kammer 14 og koger/køleren 16. Som vist passerer dette bånd gennem bunden af kammeret 14 (idet der er tilvejebragt en passende, konventionel luftsluse for at opretholde den over-35 atmosfæriske tryktilstand inden i kammeret) med henblik på at modtage og transportere individuelle emballager 54 medThe continuous boiler / cooler 16 is a conventional unit of the kind described in a sales brochure distributed by the Rexham Company in Rockford, Illinois, USA under the designation "Hydrolock Continuous Cooker / Cooler". Reference is made to this brochure. Briefly, however, the boiler / cooler device is designed to receive individual packaging of food products in order to subject these short-term high temperature sterilization followed by cooling and pressure relief to ambient temperature and pressure. In FIG. 1 and 2, it will be seen that a continuous conveyor belt 52 serves to functionally connect the inner chamber 14 and the boiler / cooler 16. As shown, this belt passes through the bottom of the chamber 14 (providing an appropriate conventional airlock to maintain the over-atmospheric pressure state within the chamber) for receiving and transporting individual packages 54 with

6 fødevareprodukt. Disse emballager transporteres derpå via båndet til koger/køleren for passende yderligere behandling deri.6 food product. These packages are then transported via the belt to the boiler / cooler for appropriate further processing therein.
Selv om der i fig. 1 og 2 er vist et emballeringsap-5 parat 40 udformet til at producere fleksible emballager af posetypen, er opfindelsen ikke begrænset hertil. Specielt kan der om ønsket også tilvebringes et noget større kammer 14a til at rumme konventionelt dåsekonserveringsudstyr 54.Although in FIG. 1 and 2 are shown a packaging apparatus 40 designed to produce flexible packaging of the bag type, the invention is not limited thereto. Specifically, if desired, a somewhat larger chamber 14a may also be provided to accommodate conventional canning equipment 54.
Her strækker det lodrette afgivelsesrør 34 sig igen gennem 10 kammeret 14a1 s øvre væg med den åbne ende af afgivelsesrøret i forbindelse med det indre af kammeret. På lignende måde er et udluftningsrør 46a koblet til kammeret 14a.Here, the vertical delivery tube 34 extends again through the upper wall of the chamber 14a1 with the open end of the delivery tube communicating with the interior of the chamber. Similarly, a vent tube 46a is coupled to the chamber 14a.
Udstyret 54 er udformet til at modtage tomme beholdere 56 gennem en med vinger forsynet luftsluse 58, hvorpå be-15 holderne fyldes ved en station 60 og forsegles ved en station 62. De færdige beholdere passerer så gennem en anden luftsluse 64 til den kontinuerlige koger/køler 16 til nedenstrøms sterilisation og køling.The equipment 54 is designed to receive empty containers 56 through a winged air lock 58, whereupon the containers are filled at a station 60 and sealed at a station 62. The finished containers then pass through another air lock 64 to the continuous boiler. cooler 16 for downstream sterilization and cooling.
Overatmosfæriske trykbetingelser inden i kammeret 20 14a etableres ved hjælp af den kraftdrevne kompressor 44a, som det let vil forstås af fagmanden.Over-atmospheric pressure conditions within the chamber 20 14a are established by the force-driven compressor 44a, as will be readily understood by those skilled in the art.
En særlig fordel ved den foreliggende opfindelse stammer fra den omstændighed, at ledningen 18 står i åben forbindelse med det indre af emballeringskammeret, som kan 25 sættes under tryk. Som en følge heraf skaber de overatmosfæriske trykforhold inden i kammeret modtryksbetingelser inden i ledningen 18, som modvirker strømning af fødevareprodukt. Ledningen (og i givet fald varmevekslerorganerne) er udformet til i samvirke med pumpeanordningen og kammerets 30 trykpålægningsorganer at etablere en i det væsentlige ensartet aftagende trykgradient langs hele længden af ledningen fra pumpeanordningen 20 til afgangsenden af afgivelsesrøret 34. Det skal i denne forbindelse bemærkes, at ledningen 18 er fuldstændig fri for kraftdrevne pumper eller lignende 35 foranstaltninger til at skabe modtryk i skarp kontrast til det anlæg, der er omhandlet i US patentskrift nr. 3.241.475.A particular advantage of the present invention arises from the fact that the conduit 18 is in open communication with the interior of the packaging chamber which can be pressurized. As a result, the over-atmospheric pressure conditions within the chamber create counterpressure conditions within the conduit 18, which discourages food product flow. The conduit (and, where appropriate, the heat exchanger means) is designed to establish, in cooperation with the pumping device and the pressure applying means of the chamber 30, a substantially uniform decreasing pressure gradient along the entire length of the conduit from the pumping device 20 to the outlet end of the delivery tube 34. It should be noted in this connection that line 18 is completely free of power-driven pumps or similar means to create a counter-pressure in sharp contrast to the plant disclosed in U.S. Patent No. 3,241,475.

Dette sikerer ligeledes, at produktstrømmen inden i ledningen 18 i det væsentlige er af proptypen med henblik på at undgå sprængning af partikler.This also ensures that the product flow within the conduit 18 is substantially of the plug type in order to avoid particle bursting.
Det har i praksis vist sig, at der kan opretholdes 5 en ensartet aftagende trykgradient, som ikke varierer mere end ca. 10 procent pr. længdeenhed af ledningen 18 sammenlignet med den samlede gennemsnitsgradient. Det vil sige, at hvis man betragter en hypotetisk situation med en ledning med en effektiv længde på 3 meter og et samlet trykfald 10 mellem afgangen fra pumpen 20 og udledningsenden af røret 34 på 1,4 ato, ville gennemsnitstrykgradienten over hele ledningen 18 være 1,4/3 ato/m eller 0,46 ato/m. Under disse forudsætninger foretrækkes det, at trykgradienten for hver 30 cm (Feet) længde af ledningen 18 inden for denne længde 15 ikke bør variere mere end 10 procent fra det samlede gennemsnit på 0,46 ato/m, eller fra 0,41-0,51 ato/m.In practice, it has been found that a uniform decreasing pressure gradient can be maintained which does not vary more than approx. 10 per cent. length unit of line 18 compared to the overall average gradient. That is, considering a hypothetical situation with a conduit with an effective length of 3 meters and a total pressure drop 10 between the outlet of the pump 20 and the discharge end of the tube 34 of 1.4 ato, the average pressure gradient over the entire conduit 18 would be 1 , 4/3 ato / m or 0.46 ato / m. Under these conditions, it is preferred that the pressure gradient for each 30 cm (Feet) length of line 18 within this length 15 should not vary more than 10 percent from the overall average of 0.46 ato / m, or from 0.41-0. , 51 ato / m.
I de tilfælde, hvor der anvendes indirekte dampfødede varmeveksleranordninger, bør damptrykket af dampen, som tilføres varmevekslerkapperne, være mindst 0,35 atm, og 20 fortrinsvis 0,35-0,7 atm under det tilsvarende produkttryk inden i ledningen 18 og varmeveksleren. På denne måde er det muligt at sikre, at der ikke forekommer nogen uønsket bratkogning (flashing) af produktet, mens man ikke desto mindre holder behandlingsbetingelserne så nænsomme som muligt 25 med henblik på at forøge produktsammenhængen og de organo-leptiske egenskaber af det endelige emballerede materiale.In the case where indirect steam-fed heat exchanger devices are used, the vapor pressure of the steam supplied to the heat exchanger sheaths should be at least 0.35 atm and preferably 0.35-0.7 atm under the corresponding product pressure within line 18 and the heat exchanger. In this way, it is possible to ensure that no unwanted flashing of the product occurs, while still keeping the processing conditions as low as possible in order to increase the product coherence and organoleptic properties of the final packaged material.

20 Derpå suges den blandede, forvarmede hachisopskrift ved tilnærmelsesvis 65° C ind i stempel fyldningskammeret i Mar-lenpumpen og pumpes til varmeveksleren med 7,3 kg/minut. Modtrykket på produktet leveres af det under tryk stående emballeringskammer. Dette kammer holdes ved 1,8 ato, hvilket 25 medfører tilnærmelsesvis 2,5 ato produkttryk ved indgangen til produktrøret fra Marlenpumpen. Der anvendes tilstrækkelig opvarmningsoverflade og længde af holderøret til at tilvejebringe opvarmning fra 65°C til fyldningstemperaturen på 124°C, mens kappeopvarmningsdampen holdes på mindst 0,35 30 atm (og fortrinsvis på 0,35-0,70 atm) under det tilsvarende produkttryk.Then the mixed, preheated hachis recipe at approximately 65 ° C is sucked into the plunger filling chamber of the Marlen pump and pumped to the heat exchanger at 7.3 kg / minute. The back pressure on the product is supplied by the pressurized packaging chamber. This chamber is held at 1.8 ato, which causes approximately 2.5 ato product pressure at the entrance to the product pipe from the Marlen pump. Sufficient heating surface and length of the holding tube are used to provide heating from 65 ° C to the filling temperature of 124 ° C while keeping the jacket heating vapor at least 0.35 30 atm (and preferably 0.35-0.70 atm) under the corresponding product pressure .
På grund af den nøjagtige styring af både modtryk og produktstrømningshastighed, som anlægget tilvejebringer, holder trykforskellen produkttrykket tilstrækkeligt højt 35 til, at det overstiger væskefasedamptrykket ved de temperaturer, produktet kommer ud for ved opvarmningsoverfladenDue to the precise control of both back pressure and product flow rate provided by the plant, the pressure difference keeps the product pressure sufficiently high to exceed the liquid phase vapor pressure at the temperatures reached by the heating surface.
